Abstract

A light guide plate according to one or more embodiments may include an incident surface that receives light, and an optical path changer on a back surface perpendicular to the incident surface. The optical path changer may reflect light to be emitted through an emission surface parallel to the back surface. The light emitted through the emission surface may form a formed image including a plane image representing a surface. The plane image may include a near imaging portion and a distant imaging portion. The plane image may have two ends included in the near imaging portion in a cross section perpendicular to the back surface and an optical axis of a light source.
